Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601544, here are decompositions:

5 + 31601539 = 31601544
17 + 31601527 = 31601544
31 + 31601513 = 31601544
71 + 31601473 = 31601544
127 + 31601417 = 31601544
137 + 31601407 = 31601544
151 + 31601393 = 31601544
197 + 31601347 = 31601544

Showing the first eight; more decompositions exist.
